Describe metahubs as collaborative design-time hubs.
Metahubs are collaborative design-time hubs used to organize shared structures, branches, publication-ready artifacts, and related ownership or membership data.
Current Implementation
The repository already contains backend and frontend modules for metahub flows, including branch handling, publication relations, memberships, template seeding, and request-aware access checks.
Architectural Role
Hold design-time structures in central schemas.
Coordinate branches and publication lifecycle.
Connect authorship, memberships, and reusable templates.
Feed publication and application runtime surfaces.
Metahubs are one of the clearest examples of the platform's current organization-first and schema-aware direction.
